Abstract:
The invention relates to a piezoceramic material with reduced lead content, based on potassium sodium niobate (PSN) and having a defined parent composition. According to the invention the manner of addition of a mixture of Pb, Nb and optionally Ag and optionally Mn gives a wide sintering range together with reproducible electrical and mechanical properties of the material.
